推荐答案
总体目标
Xcode定义了一种特殊的目标类型，可让您构建一组 即使这些目标彼此不依赖，也要立即达到目标.一个 聚合目标没有关联的产品，也没有构建规则. 相反，汇总目标取决于您想要的每个目标 共建.例如，您可能有一组产品 您想一起建立.您将创建一个汇总目标，然后 使它取决于每个产品目标.建立所有 产品，只需建立汇总目标即可.
Xcode defines a special type of target that lets you build a group of targets at once, even if those targets do not depend on each other. An aggregate target has no associated product and no build rules. Instead, an aggregate target depends on each of the targets you want to build together. For example, you may have a group of products that you want to build together. You would create an aggregate target and make it depend on each of the product targets. To build all the products, just build the aggregate target.
聚合目标可能包含一个自定义运行脚本构建阶段或一个 复制文件构建阶段，但不能包含任何其他构建阶段. 聚合目标所包含的任何构建设置都不会 解释但传递到目标的构建阶段 包含.
An aggregate target may contain a custom Run Script build phase or a Copy Files build phase, but it cannot contain any other build phases. Any build settings that the aggregate target contains are not interpreted but are passed to the build phases that the target contains.
